Yes, well the Soviet Union was also a peacemaker. In fact, so was the Roman Empire. We can look at colonialism as a peacemaker---as other countries set up arbitrary hierarchies among groups that may have fought more (no sense using valuable resources and losing cheap labor through those silly conflicts).
It's in our nature to be peacemakers because Elohim Yahweh is a peacemaker. We are also compassionate and empathetic like Elohim the Spirt. When you put them together you get justice and compassion combined, but all on the foundation of Love. However, we have a flaw in how God manifests through Humanity and that is of the ego. We can chooser to cut God off because we, like Him, have free will. With the ability to lead, comes the ability to enslave. The sword can be used to protect against wild animals and also can be used to hold hostages for ransom. This is why the Leadership role, or the Son, requires a process of which that Kingship is earned. For something to be earned it has to be available to all, which is why failed kingships are allowed to exist (such as the ones you mentioned). They're ALL here to prove a point and a point they do all make. There is only ONE King and that is the Spirit of Truth which is the Son of God, the one who died on he cross in the 1st century. He was the favored to win the role since the Beginning and he accomplished his Father's will. It's truly a blessing that most seem to not grasp or warp for their own means.
Enforced peace, by sheer power of will. We see what happens when that power is removed. So, no, I don't agree this is peacemaking. A god of war does not make peace, unless it is in god of war style---total domination. I see a common tactic is to redefine words. A purpose to war--grouping for the cause---therefore peacemaker.
Traditionally to be a father is to have children who seek your approval. Ultimately the father decides which child should lead the family. In the modern world this tradition has been eroded, but still exists. In the ancient world it was almost always a family business that provided their survival. This pattern progressed into the distant future as we see surnames like Shoemaker and Smith. My father wanted me to take on the family business of general construction, but I went into IT which is a modern choice for a son. It shows that we are in a state of Change.
But, traditionally the sons are going to be in a sort of fued for their father's approval. This is at the heart of the sibling rivalry dynamic. I guess that's why they call it feudalism, because their will be feuds among the houses that spring forth from the good deeds of generations past. Proverbs speaks about this in chapter 17 where it says " Better a dry crust with peace and quiet than a house full of feasting, with strife." That strife he is talking about is the basic cause of the feuds that make up the "game of houses" dynamic. Many science fiction and fantasy universes use this as a story environment. The Shoguns of Japan are a good example of real life fueding houses all connected to a centralized figure. A socially ran governmental hierarchy.
A more modern example would be the American Presidential race. Even today the role of leader requires the rigors of warfare to determine the person in command. No, Romney and Obama didn't kill each other, but most would agree that it was a war. There is no difference in the Holy Family we are just acting in accordance with our design, but the TOP LEVEL Leader was already chosen and that is the Son of God who died on the cross. Even the current leader of America kneels before him in obeisance. The American public is appalled at his lack of church attendence while in office, however they are overeacting because he deals with a lot, but it shows how much we still care about that sort of thing.
Have fun!
I wouldn't have it any other way.
